In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of simple in structure, impact it is small with
And highly practical pump head.
To achieve the above object, the utility model provides following technical solution：A kind of pump head of hot water circuit canned motor pump,
Including ontology, the ontology is equipped with water inlet and water outlet, and the water inlet includes outer flow passage and inner flow passage, outer flow passage and interior
Arcwall A and arcwall B is equipped between runner, inner flow passage is equipped with arcwall C, arcwall A and arcwall C homonymies and and arc
Wall B heteropleurals, arcwall A and arcwall B are in outer male structure, and arcwall C is in concave inward structure.
The utility model is further arranged to：The inner wall of the water outlet is in concave inward structure, and water outlet includes input terminal
And output end, and the internal diameter of water outlet gradually increases from input terminal toward output end.
The utility model is further arranged to：The ontology, which is equipped with, places annular groove, places annular groove and is equipped with baffle ring,
Baffle ring includes baffle ring A and baffle ring B, and baffle ring A is contradicted with the inner wall for placing annular groove, and the height of baffle ring B is more than the height of baffle ring A
Degree.
By using above-mentioned technical proposal, advantageous effect：（1）Ontology be equipped with water inlet, water inlet include outer flow passage and
Inner flow passage, is equipped with arcwall A and arcwall B between outer flow passage and inner flow passage, inner flow passage is equipped with arcwall C, arcwall A and arc
Shape wall C homonymies and with arcwall B heteropleurals, arcwall A and arcwall B are in outer male structure, and arcwall C is in concave inward structure, above-mentioned
Structure setting reduces the impact in the hydraulic pressure inner loop water route of water inlet, and influences the continuity of interior circulation waterway, it is ensured that right
The lubrication and cooling effect of structure in pump；
（2）The structure setting of water outlet has reduction to a certain extent to the hydraulic pressure of water outlet, improves the controllable of hydraulic pressure
Property, and then improve practical function；
（3）Ontology, which is equipped with, places annular groove, places annular groove and is equipped with baffle ring, improves impeller and have when rotated well
Self-priming effect.
